Engineering Systems Integration
Examples of scope include: work planned or accomplished; processes and
procedures planned or accomplished; organizational entities involved or not
involved; transactions to be completed or to be ignored; interactions or integrations scheduled or left unscheduled; items budgeted or not budgeted;
information exchanged or kept confidential; ideas on an agenda to be discussed or left out; and concepts considered germane versus passed over or
disregarded.
Carrying the metaphor of the chess match further, scoping refers to the
rules of play. There are differences between tournament play (with penalties
to player who distract their opponents, e.g., receiving calls on a cell phone,
recording moves of pieces) and clocking time for beginning and ending
play. The scoping of procedures and rules most often have only peripheral
bearing on the boundaries of the game board. In essence, scoping guides
the “work” (i.e., game-play) that is to be accomplished in connection with
the game.
Defining the boundary of a product or service provides general guidance
from which to scope the development and integration project. Scoping a
project helps determine what should be included and not included within
the limitations set by the product or service boundaries. Scoping a work
effort assists the project team in making the myriad of decisions that constantly present “opportunities” to stray from the project’s objectives. Scoping
at the rule-level of carrying out project work reinforces the high-level policy
and management guidance that is offered to show the path that is acceptable and presents the least expensive, most time-efficient way to complete
the project.
Boundary Conditions
A condition is the circumstances that encompass an object; the factors that
affect the manner and ways in which the object interacts; the situation in
which the object operates; or the terms under which an object behaves. An
object is influenced by its sensitivities to conditions. If an object is burdened
by excess mass due to ice accumulation and adherence (i.e., sticking) to its
exterior surface (e.g., wings of an aircraft), then ice is a factor for take-off and
flight safety. The physical boundary of an aircraft’s wings may interact with
that of the atmosphere and result in ice “forming” on the wings. The boundary condition for the formation of ice may be temperature, humidity, and
airflow over the wing’s surfaces. The physics of icing metallic surfaces begins
with nucleation centers that occur due to contaminants, edges, corners, and
in general, surface roughness. Increasing the temperature, lowering the
humidity, or increasing airflow may prevent ice formation on the wings.
The boundary condition for de-icing of the aircraft wings is then potentially
